Time-out Timer:

The Time-out Timer feature prevents channel congestion and helps extend battery life. The radio will sound a warning tone if the Push- To-Talk button is pressed for 60 continuous seconds and will stop transmitting.

Scan (Optional)

Some M-Series models have Scan. Scan allows you to monitor the radio’s pro- grammed channels and code. When the radio detects someone talking, it stops scanning and locks in on the active chan- nel. It allows you to listen and talk back automatically to the person transmitting without having to switch channels.

Note: To communicate in scan, your radio must be set to the same frequency and code as the other radio(s) in your group.

To Use Scan Feature

1.Move the Channel Selector knob to the “s” position (Fig. N). The radio will scan the radio’s programmed channels and code in sequential order.

2.When the radio detects someone talking, you will hear the message.

3.Press Push-To-Talk button to talk back on the channel.

In scan,you will always transmit back to the channel which last sent a message.
